Qtl is - Study guides, Class notes & Summaries

Qualitative traits Ans: controlled by one or a few loci; discrete phenotypes (eye colour, coat colour, seed colour, seed texture, blood type, colourblindness etc) Quantitative traits Ans: controlled by multiple loci (also called polygenic traits); continuous phenotypes (height, weight, racing speed, milk yield, temperature, intelligence, temperament, schizophrenia - threshold trait) --> the range is measured as variation --> many loci contributing to the phenotype P = G + E An...

How many loci are involved in quantitative traits? Ans: 10s, 100s, 1,000s of loci What do the many loci involved in a quantitative trait do? Ans: Most have a small effect on the overall function, some have larger parts and can be found. QTL is? Ans: quantitative trait loci QTL Detection Ans: Finding a polymorphism in the genome that is associated with a difference in phenotype. Polymorphism Ans: 2 or more variant forms of a specific dna structure 2 SNP Ans: single nucleotide poly...
